Rillet: The ERP Built by Accountants, for Accountants
Co-founded by former N26 executives Nicolas Kopp (CEO) and Stelios Modes (CTO), Rillet is designed to overhaul outdated enterprise resource planning (ERP) systems that rely on manual processes and disconnected spreadsheets.
Their goal is clear: empower lean, high-performing finance teams to close books in days, not weeks – and scale operations from startup to IPO.
Since launching, Rillet has signed over 200 customers and doubled ARR in just the past three months. Its clients, including unicorns like PostScript and hypergrowth firms like Windsurf, report dramatic reductions in book-closing timelines and finance headcounts – powered by Rillet’s smart general ledger and native AI integrations.
“Finance teams shouldn’t be stuck with 20th-century tools,” said Kopp. “Rillet is rebuilding ERP for today’s world — intelligent, scalable, and ready for the demands of fast-growing businesses.”

AI-First Architecture Meets Real-Time Financial Intelligence
Unlike traditional ERP systems from legacy giants like Oracle NetSuite, Microsoft Dynamics, or Sage Intacct, Rillet’s architecture is AI-first and real-time. Native integrations streamline data into a central intelligent ledger, allowing in-platform AI to automate workflows, support collaboration, and surface key financial metrics instantly – not weeks later.
This architectural innovation has made Rillet the go-to platform for modern CFOs, giving them tools for faster decision-making, enhanced audit readiness, and strategic planning.
“Rillet is the clean-slate ERP the finance industry has long needed,” said Rampell of Andreessen Horowitz. “It’s bringing AI to finance in a way that’s meaningful and execution-driven.”
Built by Finance Pros, Not Just Technologists
Rillet’s team is stacked with former controllers, CPAs, and finance leaders from EY, PwC, and high-growth startups. This accountant-first DNA permeates every feature, implementation, and customer success playbook — giving clients confidence in adoption and scalability.
“Rillet doesn’t just modernize accounting software,” added ICONIQ’s Pierrepont. “It redefines what finance teams can accomplish when freed from outdated systems.”
Rillet at the Crossroads of Talent and Automation
As 75% of today’s accountants are expected to retire in the next 15 years, and with 80% of routine finance tasks ripe for automation, the company is positioned at the intersection of talent shortage and tech opportunity. The platform enables finance teams to do more with less – shifting focus from manual work to strategic impact.

- Deeper integrations across the fintech stack
- Scalable implementations across high-growth and global organizations
- Hiring in engineering, customer success, and implementation
- Development of a collaborative ecosystem where AI agents and finance pros work side by side
With several clients poised to go public using Rillet, the company aims to prove that the next generation of IPO-ready companies can grow on truly AI-native infrastructure.
“We’re building the financial operating system for the next decade,” concluded Kopp. “Rillet is the infrastructure that helps ambitious companies win – with speed, insight, and scale.”
